I made this gorgeous resin bowl with my 16 oz split cup and I'm so in love with it! Let me know what you guys think and if you'd like to see more split cup resin pours. As a note, these split cups aren't intended for resin but can be used with resin. I don't clean mine, I just let it drain and dry, but you could clean it out with alcohol while the resin is still wet if you'd like :) | Mixed Media Girl
